ECG: left vs. right bundle block "WiLLiaMMaRRoW":W pattern in V1-V2 and M pattern in V3-V6 is Left
bundle block.M pattern in V1-V2 and W in V3-V6 is Right bundle
block.
· Note: consider bundle branch blocks when QRS complex is wide.

Murmurs: systolic typesSAPS:SystolicAorticPulmonicStenosis
· Systolic murmurs include aortic and pulmonary
stenosis.
· Similarly, it's common sense that if it is
aortic and pulmonary stenosis it could also be
mitral and tricusp regurgitation].

Heart
compensatory mechanisms that 'save' organ blood flow during shock
"Heart SAVER":Symphatoadrenal systemAtrial natriuretic factorVasopressinEndogenous digitalis-like factorRenin-angiotensin-aldosterone system
· In all 5, system is activated/factor is released

Murmurs: right vs. left loudness "RILE":Right sided heart murmurs are louder on Inspiration.Left sided heart murmurs are loudest on Expiration.
· If get confused about which is which, remember LIRE=liar which will
be inherently false.

Apex beat: abnormalities found on palpation, causes of impalpableHILT:HeavingImpalpableLaterally displacedThrusting/ Tapping
· If it is impalpable, causes are COPD:COPDObesityPleural, Pericardial effusionDextrocardia
